How to create lighting for an LED strip?
Idle Chit-chat

I am not familiar with all the LED terms you used, so I just answered the bolded question. BR is a good engine, and although Cycles might be better, there is a great way to do it in each. Similarly, I will include instructions for both.

Blender Render

I believe it might be best to use a point/spot lamp inside the mesh and control the color/strength from the lamp settings AND shader Diffuse color settings.

Add a lamp inside your cubic mesh. Set the color and strength to the desired effect. Add a shader to the mesh. Change the Diffuse color to correspond with the lamp color. Change the Emit strength to 2, the max. Here's the key: Uncheck Traceable in the settings. Procedure described and explained further here around 40:00.

Cycles

Use an Emission shader and set the color and strength as desired. You will need to set the strength in the hundreds or thousands to see it light up. That's it; ta-da!

Hope this helps and happy Blending!
